Subject[PATCH v26 0/5] Add initial zynqmp R5 remoteproc driver
R5 is included in Xilinx Zynq UltraScale MPSoC so by adding this
remotproc driver, we can boot the R5 sub-system in two different
configurations -
* Split
* Lockstep

The Xilinx R5 Remoteproc Driver boots the R5's via calls to the Xilinx
Platform Management Unit that handles the R5 configuration, memory access
and R5 lifecycle management. The interface to this manager is done in this
driver via zynqmp_pm_* function calls.

- add prepare and unprepare to handle Xilinx platform management's
request_node and release node using each core's list of srams
that is constructed in each core's zynqmp_r5_probe.
- add new field sram to zynqmp_r5_rproc to store each core's srams
being used as described in device tree. This helps to reduce unneeded looping
of the sram prop in device tree. As now only zynqmp_r5_probe has to parse
and validate each core's sram property. The ensuing prepare, unprepare
and parse_fw logic are now much simpler.
- similarly add 'size' field to struct sram_addr_data to simplify
prepare, unprepare and parse_fw.
